he probably turned to drugs and alcohol when he realized he'd actually fucked denise richards....NASTY!

Smart fellow. Good week to go into rehab with the latest Paris scandal going on. By Monday no one will even remember he's there.

Or, conversely, maybe the addiction is what caused the divorce and subsequent end to his relationship with Denise.

He's had it rough lately, give him a break. At least he's trying to make himself better.
